Fabian,
Here is another way:

lnh = fopen('MyExe.exe')
if lnh > 0 then
   lcdata = fread(lnh,20000)
   if at(strconv(strconv('Microsoft Visual FoxPro',1),5),lcdata) > 0 then
      * VFP application
   else
      * it is not a VFP EXE
   endif
   =fclose(lnh)
endif

I tested this using very small EXEs (9K and 17K) and one "normal" VFP EXE (9.2 MB). The 20000 bytes worked for both. The VFP information is stored near the beginning of the EXE.

HTH.
